The function g(x)= x^ square root of 1+x is neither an even function nor an odd function

The function is given as

g(x)= x^ square root of 1+x

Rewrite the above function equation properly

So, we have

g(x) = x^(√x+1)

Calculate g(-x)

So, we have

g(-x) = -x^(√-x+1)

Evaluate

g(-x) = -x^(√-x+1)

Calculate -g(x)

So, we have

-g(x) = -x^(√x+1)

In the above computations;

g(x) does not equal g(-x) and -g(x)

Hence, the function g(x)= x^ square root of 1+x is neither an even function nor an odd function

Step-by-step explanation:

The area of the computer chip is 2.44 x 10^-15 square units

The area of a shape is the amount of space on the shape

The dimensions of the computer chip are given as

7.18 x 10^-7 and 3.4 x 10^-9

The area of the computer chip is the product of the dimensions of the computer chip

So, we have

Area = Length x Width

This gives

Area = 7.18 x 10^-7 x 3.4 x 10^-9

Rewrite as

Area = 7.18 x 3.4 x 10^-7 x 10^-9

Evaluate the products

Area = 24.412 x 10^-16

Rewrite as

Area = 2.4412 x 10^-15

Approximate

Area = 2.44 x 10^-15

Hence, the area of the computer chip is 2.44 x 10^-15 square units

The result to the equation given by rounding this to the nearest ten-thousandth is 4.0000.

Rounding off means simplifying a number by keeping its overall value but moving it closer to the next number. It is used for whole numbers and decimals with tens, hundreds, thousands, and so on.

If the digit in the smallest spot is less than 5, it is left alone. Rounding down occurs when any number of digits then after the number become zero. If the digit inside the smallest place is larger than or equal to 5, it is multiplied by +1.

Answer:

11.1111 for 40 km

279.4 for 11 in

Step-by-step explanation:

Answer:

7. 17

8. -7

9. 64/3 or 21 1/3

Step-by-step explanation:

7. 3x-4 and the value of x is 7. Plug 7 into the x values in the expression that is given.

3x-4  --> 3(7) - 4

When simplified, 3(7) - 4 becomes 21-4 which is 17.

8. -5x+8 and the value of x is 3. Same as before, but this time you'll plug 3 into the x values in the given expression.

-5x+8 --> -5(3) + 8

When simplified,  -5(3) + 8 becomes -15+8 which is -7.

9. 10x+18 and the value of x is 1/3. Plug in 1/3 into the x values in the expression.

10x+18 --> 10(1/3)+18

When simplified, 10(1/3)+18 becomes 10/3+18. To solve this, turn 18 in a fraction over 3. 3x18=54 and that gives you the numerator. 10/3+54/3= 64/3. If you wanted it in a mixed fraction, it would be 21 1/3.

The variable w is as follows:

We have to find the variable w in the equation.

-61 = 8 - 1 / 3(12w + 42) - w

subtract 8 from both sides of the equation

-61 = 8 - 1 / 3(12w + 42) - w

-61 - 8 = 8 - 8 - 1 / 3(12w + 42) - w

-69 = - 1 / 3(12w + 42) - w

69 = 1 / 3(12w + 42) + w

Therefore,

[tex]\frac{1}{3(12w+42)}+w[/tex] = 69

[tex]\frac{1+3w(12w+42)}{3(12w+42)}[/tex] = 69

[tex]\frac{1 + 36w^{2} +126w}{3(12w+42)}[/tex] = 69

cross multiply

1 + 36w² + 126w = 2484w + 8694

36w² + 126w - 2484w - 8694 + 1 = 0

36w² - 2358w - 8693 = 0

using,

[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

a = 36

b = -2358

c = -8693

Hence,

[tex]\frac{2358+\sqrt{(-2358)^{2}-4(36)(-8693) } }{2(36)}[/tex]  and [tex]\frac{2358-\sqrt{(-2358)^{2}-4(36)(-8693) } }{2(36)}[/tex]

Therefore,

[tex]w = \frac{393+\sqrt{189221} }{12}[/tex] and [tex]w = \frac{393-\sqrt{189221} }{12}[/tex]

The interest the friend will have after her college graduation in 4 years is $240 and an exponential model is not reasonable for this situation.

The formula to be used to is given as :

            I = Prt (1)

where, I = simple interest

          P = principal amount or amount initially deposited.

          r = annual interest rate

         t = time

According to the question we have been given that

         P = $1000

         r = 0.06

       t = 4 years

Putting the required values in equation (1) we get

        I = 1000*0.06*4

        I = 240

Thus $240 interest the friend will have after her college graduation in 4 years.

Using greatest common factor (GCF), Mr. Raymond should put 6 students in each group. If that happens, he will have 3 groups of 6th graders and 4 groups of 7th graders.

The greatest common factor (GCF) of a set of numbers is defined as the largest common positive integer that divides each number into equal parts with zero remainder.

If Mr. Raymond has 18 6th graders students and 24 7th grader students he wants to put in equal groups wherein each group will have students of only one grade level, find the GCF of 18 and 24 to find how many students he will put in each group.

18 : 1, 2, 3, 6, 9, 18

24 : 1, 2, 3, 4, 6, 8, 12, 24

GCF = 6

Hence, he should put 6 students in each group.

let x - 4z = 8 be equation (1), 12x - y - 6z = 8 be equation (2) and 42x + 3y - 2z = 8 be equation (3)

x - 4z = 8

y = 42z + 88

42x + 3y - 2z = 8

The length of the third side of the right triangle is 12.65 feet.

It states in a right triangle the square of the length of the hypotenuse is equal to the sum of squares of the lengths of the other two sides of the right-angled triangle.

We have,

Right triangle:

Side = A = 6 feet

Hypotenuse = h = 14 feet

Let the 3rd side be = M

Applying Pythagoras theorem:

h² = A² + M²

14² = 6² + M²

196 = 36 + M²
M² = 196 - 36

M² = 160

M = √160

The value of k in function g of x is x-2.

A function in mathematics can be defined which from a set X to a set Y that is to allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and range or sometimes refer to the codomain of the function , respectively.

In mathematics, a function is an expression, rule, or law that establishes the relationship between a single variable (the independent variable).

In the given question,

function of x = (1)* (-x+6)

and function of g = g of x = k

now the solution of equation is,

f (x) = g (x) is x = 4.

taking,  putting x =4 in (1)* (-x+6)

=> x = -4 + 6 = 2

now for g of x to be 4 the value of k should be x-2

as when x = 4 , g of x = x-2 = 4-2 = 2 = f of x

Thus, The value of k in function g of x is x-2.
